Vacuum Interrupters Inc. introduces the MAC-TS4 vacuum interrupter tester, the third generation test set using its patented technology for determining the condition of vacuum interrupters in the field, shop or laboratory.
Until now, the accepted field service test for vacuum interrupters has been a simple Go/No-Go test performed with an AC high potential test. Today, testing with our Magnetic Atmospheric Condition (MAC) test sets can prevent unnecessary damage to your circuit breakers and contactors by predicting the usable life of the vacuum interrupter.
If you're looking for a meaningful vacuum interrupter test, take a look at the outstanding capabilities of our new MAC-TS4 vacuum interrupter tester (aka vacuum bottle tester) which can be used in the field, shop or laboratory.
Utilizing the Penning Discharge Principal, our MAC-TS4 vacuum interrupter test set can easily determine the pressure inside a vacuum interrupter and; along with wear and number of operations, predict the usable life of the vacuum interrupters used in your circuit breakers and contactors. Until now, this type of testing could only be done at the assembly plant.
This video explains the therory and science behind vacuum interrupter testing with the MAC-TS4 test set.
Here is a link to an operational demonstration video showing the setup and testing of vacuum interrupters using the MAC-TS4 test set.
Flexible Magnetic Field Test Coils
Flexible magnetic field coils are available for testing vacuum interrupters while installed in switchgear and magnetic field coil test fixtures are available for testing when removed.
Our unique, patented flexible magnetic field test coil enables vacuum bottle interrupters to be tested in-place, while installed in your circuit breaker or contactor. The flexible magnetic field coil is available in various lengths to accommodate most applications, and is used in conjunction with the MAC-TS4 vacuum bottle - interrupter tester.
Rigid magnetic test coil for GE PowerVac circuit breakers
New, rigid magnetic coil for the MAC-TS4 vacuum interrupter test set allows technicians to test vacuum interrupters in GE PowerVac breakers in place without disassembling.
Used in conjunction with the MAC-TS4 test set, the PowerVac rigid magnetic field coil slides over the PowerVac pole assembly, allowing the technician to determine the interrupter's remaining lifespan without removing the vacuum interrupter.
The portable, rigid magnetic coil used in testing vacuum interrupters installed in PowerVac circuit breakers is the first of many breaker-specific coils currently being developed.
Magnetic Field Test Fixtures
For testing of individual vacuum interrupters that have been removed from a circuit breaker or contactor, a magnetic field coil test fixture is used in conjunction with the MAC-TS4 vacuum interrupter test set. Magnetic field coils are available in various sizes to accommodate most vacuum interrupters.
Completely Self-Contained
Completely self-contained, the MAC-TS4 is provided with everything required to test your vacuum interrupters in the field, shop or lab. It incorporates high-voltage power supply, back-lit LCD display, and built-in thermal printer; and is furnished with a complete set of test leads.
Computer Interface and Windows®-Based Software Provide Additional Capability
USB connection and the included Windows®-based software allows technician to control operation of the MAC-TS4 with an external pc, download stored test results, and generate test reports.
